This fast-moving compilation gives you the crash course in Miles. The coiled energy of "Now's the Time," with quick and intense solos by Davis and Charlie Parker, hints at all the innovations to come. Gil Evans' ghostly strings on "The Pan Piper," the '60s quintet in fearless full flight on the hyperkinetic "E.S.P.," and the funky jazz-rock free-for-all on the clattering "Black Satin" fit perfectly together thanks to Davis' relentlessly questing spirit and detached, economical tone.
